TOOL.

Application filed November 22, 1915, Serial No. 62,815. Renewed October28, 1916.

To all whom it may concern:

Be it known that I, DAN B. SWIGKARD, a citizen of the United States,residing at Galva, in thecounty of Henry and State of Illinois, haveinvented certain new and useful Improvements in Tools; and I do here bydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention is a tool adapted for use as pliers, or a pipe wrench, ora cutting implement.

In tools of the character described in my pending application, Serial N0. 37,203, which was filed June 30, 1915, it has been found that thelong sweep of the free handle member permits of too great power to beapplied to the material operated upon for some class of work, resultingin the crushing of the material, such for example as a ipe. p Thisinvention is designed to control the action of the pliers by means of astop device, which, while permitting of increased power over tools ofordinary character, which are permanently pivoted at a predeterminedpoint at the rear of the jaws, prevents injury to the material to beoperated upon by the control of the leverage power.

The invention includes means for eifecting lateral and endwiseadjustment of the jaws by varying the limits of the swinging movement ofone lever member with relation to the other lever member, when said at aplurality of pivotal points.

The tool' embodies a plurality of lever members so connected that onemember has a swinging movement with relation to the other member and thejaws are adjustable laterally and endwise by mechanism carried by one ofthe members, associated with means on one of the members to limit thelendwise and lateral movements of said mem- This invention issusceptible of many embodiments of construction and the right isreserved to make such changes and alterations as fairly fall within thescope of the appended claims.

In the drawings :Figure l is a side elevation of one form of the devicedisclosing a type of wire cutter. Fig. 2 is a view of the other side ofthe device of Fig. 1 except Specification of Letters Patent.

Serial No. 128,347.

that the wire cutter is disclosed on a link member. Fig. 3 is a sideelevation of one member of the device of Fig. 1. Fig. 4: is a sideelevation of another embodiment of the device. Fig. 5 is a sideelevation of still another embodiment of the device.

The structure illustrated in Figs. 1 and 2 is shown as comprising twomembers. One member comprises a handle 1, a jaw 2, and a nib 3 formed onone edge thereof. The other member embodies a handle 4 and a jaw 5. Thismember is shown in Fig. 3, provided with an enlarged portion at thepoint of crossing of the members 1 and 4, said enlarged portion formingan enlargement 6 to provide for a transversely arranged slot 7.

The structure is shown provided with a plurality of links 8, 9. The link8 is illustrated in Fig. 1 as provided with an offset 10, the body ofthe link being shown elongated to extend from the jaw 5 of one member tothe rear of the jaw 2 of the other member, to permit the offset 10 to bepositioned above the jaw 5. The link 9 is similar in all substantialparticulars to the link 8, except that it is provided with a notch 11 onone edge to cooperate with the straight edge 12 of the handle 1 where itis directed angularly to form the section which crosses the angularportion of its opposing handle 4. This notch 11 and angular portion 12form a cutting edge for severing wire'or other materials. In likemanner, the nib 3 cooperates with the edge 13 of the handle member 4 toserve as a wire cutter.

In Figs. 1 and 2 the handle member 1 is shown provided with a yoke 14serving as means to house a threaded thumb nut 15 which is adapted toengage a threaded bar 16. The bar is pivotally connected to the offset10 as at 17 and has slidable connection with the yoke 14, the nut 15serving as limiting means for the slidable connection of the bar 16. Thelinks 8 and 9 are pivotally connected with the jaw 5 at substantiallythe central portion thereof by means of the pivot 17, which extendsthrough the jaw 5 and connects with said links 8 and 9 near one endthereof. Near the opposite ends of the links 8 and 9 there is providedanother pivot 18 which passes through an aperture in one member, such asthe an lar portion of member 1, and through t e slot 7 of member 4,thereby securing both links for simultaneous movefreely movable handle4, enables the operator to control the leverage action of the devicewhen applied to a structure to be operated upon.

In Fig. 4, the yoke 14, is shown of a slightly different construction tohouse a rack bar 19 with which cooperates a worm 20 mounted in therecess 21 of-the handle member 1.

This arrangement places the means for adjusting the jaws 2 and 5' at aconvenient position'for operation by the thumb ofthe user, and presentsa smooth surface to the top of the bar 19 which 0bviates the risk ofinjury to the teeth or threads of the adjusting bar.

In Fig. 5, the member 4 and the jaw 5 are of substantially the sameconstruction as those illustrated in Figs. 1, 2 and 4. J aw 2, however,is provided with a shorthandle member 22 terminating in a threaded endadapted to be engaged by the threaded nut 23 mounted upon the yoke 24depending from a supplemental handle member 25. This member 25 is shownpivotally connected at 26 with the ofiset 10 of the links 8 and 9.

The operation of the tools of thevarious embodiments is substantiallythe same, with varying facilities for controlling the action of the jawsto meet the conditions under which thevarious tools are designed to beused.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States, is 1- 1. A tool of theclass described comprising a pair of members each having a jaw, a pairoflinks arranged at the sides of-the jaw of one member, means to pivotsaid links to said jaw at the point in advance of the crossing of saidmembers, one of said members belng provided wlth a slot, and

means extending through said slot to connect the plurality of said linksand said members.

2. A tool of the class described compris- Gopiesot this patent may beobtained for five cents each,

ing a pair of members each having a jaw, one of saidmembers having aslot arranged transversely thereof near the rear of its 7 jaw, aplurality of elongated links, means to connect one end of the links toone jaw near the central part thereof, means to connect the other end ofthe links through the slot of one -member to permit-of limited swingingmovement of the member and ad" justable means to vary the operativeposi' tion ofthe jaw.

8. A tool of the class described comprising a pair of members eachincluding a handle and jaw, one of said members having a slotarranged-transversely thereof near the rear of its aw, a pluralityofelongated links having an ofi'set, means to connect one end ofthelinks to one jaw,-means to connectthe other end of the linksrthrough onelinkto one memberin advance of the crossing of themembers,meansto-pivotally connect said link to the-other member at'the crossingof said members to have-an edge of said crossing member cooperate withthe notch of said link at predetermmed intervals to serve as-acutter,and means to connect said link to the-handle of one member.

5. In a tool of'the classdescribedcomprlsing a 1)2111 0t members eachlncludlng a handle and a aw, one of saldmembers stantially the pointwhere it crosses 'the other member, a link providedwith a; notchintermediateof its endsto cooperate'with the enlargement and serve as acutter, means 'to'plvotally connect said link to the aw of' one member,and pivotal -means passing through said slot to connect said link withthe members at the crossing thereof.

In testimony whereof, I aflixmy signature, inpresence of two witnesses.
